An NFL betting spreadsheet is a structured tool that helps you manage NFL numbers with discipline. It goes beyond a simple tracker as it imports odds, dismantles the bookmaker’s margin, and provides you with the fair probabilities. The spreadsheet helps you compute expected value, guides your bet size, and maintains a record of every bet you make. With a comprehensive one, you can track closing line value, assess returns, and manage your bankroll.
At NXTbets, we offer tools and resources to help you create a solid NFL betting spreadsheet. In this guide, we will provide a step-by-step process on how to make a spreadsheet and a sample for your reference. Whereas the NFL betting spreadsheet does not guarantee a win, it can increase your chances of success.
The NFL betting spreadsheet converts raw market prices to a vig-free math you can rely on. It offers you a consistent process for staking, pricing, and reviewing your NFL bets.
Objectives
You will have bookmaker-free probabilities.
You will be able to estimate the edge and expected value.
It enables you to manage stakes using fixed units or Kelly.
With it, you can log bets and evaluate the closing line value, investment returns, and calibration.
It also flags quotes and duplicate games automatically.
Use Cases
Use the NFL betting spreadsheet for tight pregame checks and early-week card building.
Use it to compare lines across sportsbooks and identify the best price.
You can also use it to export a picks board for your posts.
Additionally, use the spreadsheet to monitor season-long ROI and bankroll.
Limits
Remember that the NFL betting spreadsheet does not predict outcomes or injuries. It also does not guarantee profit. The spreadsheet only standardizes your approach by grounding it in data analysis and review of results. It also enforces discipline, enabling you to make more informed and repeatable choices.
Download and Quick Start (CTA)
We can get you started with a simple template that you can refine over time.
Open the Settings tab to set your bankroll and unit.
Paste odds from two to five sportsbooks into Odds_Raw.
Verify the names of teams.
Select the correct week.
Choose your base unit size.
Contact us if the template misbehaves or if you need help.
The Data You Will Need
You will need accurate data inputs to obtain reliable calculations. Below are crucial components you need to develop your NFL betting spreadsheet:
Minimum Viable Inputs
You must have current odds for moneylines, spreads, and totals from at least two sportsbooks. Include the name of the sportsbook and a timestamp for every snapshot. Paste the lines in a consistent system with the home and away designations.
Next, insert your bankroll and your base unit size so that your stakes can be calculated correctly. Note both the current and opening prices if you can, to study the movement.
Recommended Extras
Maintain a record of closing lines to determine the closing-line value and calibration.
If you want to measure edge, incorporate your model’s fair lines or simple power rating.
Similarly, monitor weather forecasts, injury reports, and late status updates.
Study sportsbooks’ rules like push rules, overtime handling, and juice difference.
Optional Props Module
Should you add player props later, record player availability, and settle rules. Link a trusted stats feed for volume and verification. Do not forget to keep props on a separate tab to protect the ROI figures and main CLV. Apply settled codes to avoid disputes.
Sheet Architecture - Tabs and What Goes Where
The NFL spreadsheet can only work best if every tab has a clear role. A strong structure will keep your data organized, math clean, and workflow efficient. Here is how every part fits together:
Settings
This is the control room. Here, you enter your bankroll, unit size, no-bet band, and the Kelly fraction. Choose a week and timezone, and alternate between American and decimal odds. These will flow through every calculation you make.
Odds_Raw
This tab is where you paste the oddsmakers’ quotes. Include moneylines, spreads, and totals, with a detailed timestamp. Monitor the sportsbooks’ names and ensure you maintain a consistent order of teams.
Odds_Clean
This allows you to convert American odds to decimal. From there, you can calculate the implied probability and remove the vig. This gives you fair odds in both formats that you can work with. The clean data in this tab is the grounding for the expected value and edge.
Teams
Maintain an authoritative list of team names, their abbreviations, and divisions. That will avoid mismatches and ensure your formulas connect correctly.
Projections
This is where you load your model’s driven lines or fair probabilities. It is best to add version dates to enable you to review how the ratings change.
EV_Calc
This is the engine of the spreadsheet. It calculates expected value, betting edge, and the recommended stakes. It also flags conflicts, duplicates, or highlights stale data.
Bankroll
This section enables you to manage your bankroll balance and monitor drawdown alerts and exposure. The limits keep your staking disciplined and protect you against overbetting.
Picks_Log
In this tab, you log every bet with the details of the stake, sportsbook, price, closing line, closing line value, result, and returns. Snapshot the freeze odds when you bet.
Dashboard
The dashboard shows you the sortable board of the best edges. You can use filters for edge threshold, books, and weekly reports. The trend tiles offer a summary of win rate, closing line value, and the ROI. For quick sharing, export clean boards.
Step-by-Step Build Tutorial
Develop your sheet step by step, test and refine it over time. The order below can help you avoid errors and ensure every formula links properly.
Step 1: Import Odds
Paste raw lines from two to five sportsbooks into the Odds_Raw. Include the name of the betting site, spread, totals, moneylines, home and away designations, and a timestamp. Use Power Query for reliable imports.
Step 2: Convert to Implied Probabilities
Next, convert American odds to decimal odds.
For positive odds (+); Decimal odd = 1 + x/100.
For negative odds (-); Decimal odd = 1 + 100/x.
The implied probability = 1/decimal odd
Step 3: Remove the Vig
Calculate the p1 and p2 from the implied probabilities for two-way markets. After that, normalize:
p1′ = p1 / (p1 + p2)
p2′ = p2 / (p1 + p2)
FairDec = 1 / p’
Convert the FairDec back to American for easy readability.
Step 4: Compare to Your Fair
Pull the ratings from Projections or your model. Calculate the edge by using the formula Edge = p_model − p_market_vigfree.
Note the sign and magnitude; tag lines with limited data.
Step 5: Expected Value per $1
Let the Dec act as the market decimal price and p_model your probability.
EV = p_model * (Dec – 1) – (1 – p_model)
Look for the EV above your no-bet band for review.
Step 6: Stake Sizing
Use the Kelly: f* = (b*p – q) / b where b = Dec – 1 and q = 1 – p.
Apply half- or quarter-Kelly and an absolute exposure limit per game.
Step 7: Log and Monitor
Freeze the odds snapshot as you make your wager. Record the stake, site, line, and timestamp. After settlement, add the closing line, outcome, and net. Auto-update the ROI and CLV fields.
Step 8: Dashboard and Filters
Filter by key numbers (±3, ±7), edge, and book. Add duplicate-game warnings and stale-data flags.
How to Use the Spreadsheet Each NFL Week
Work with every NFL week as a short project. Ensure your alerts and backup sources are active.
Early Week (Mon–Wed)
Enter openers and early market quotes as soon as they are published. Compare prices in the market to obtain fair lines. Tag games that lie on or close to the key numbers. Similarly, develop a preliminary card and mark the lines you will track.
Market Watch (Thu–Sat)
Analyse the market by studying and updating weather forecasts, injury reports, and last-minute breaking news. After every significant update, rerun your edge. Move your bets as the market goes beyond your edge threshold. Use reasonable staged entries for the line you believe will improve. Keep the rationale and brief notes for every action.
Gameday (Sun)
Confirm last-minute weather and final inactive lists. Refresh the odds at least fifteen minutes before the kickoff. Finalize your stake sizes and use bets from the spreadsheet. Freeze and log the odds snapshot as you make the placement. Record the exact price and betting site for closing line monitoring.
Post-mortem (Mon)
After the game, key in the results and closing lines. Review the closing line value versus the ROI and evaluate model calibration. Note where the line movement or news affected results. Depending on the calibration and volatility, adjust your unit size, no-bet band, and Kelly fraction.
Strategy Tips to Maximize Real Value
Prioritize actions that offer repeatable value. The tips below can help you measure skill, protect your bankroll, and capture edges. Use them consistently every week.
Line Shopping
Collect two to five quotes while prioritizing price over promotions. Use the price differences to minimize juice and obtain a better spread. Keep a record of where you obtained the price and why.
Key Numbers
Your goal should be betting on or near the key numbers like 3 and 7. Even a small edge that puts you past a key number is better than a marginal percent edge. Record bets near key numbers and avoid the thin edges that pivot on them.
Pass Rules
Define clear pass rules. Avoid betting if the edge is below the threshold. It is also best to avoid betting when the site’s rules are unclear or the news is unresolved. For small expected values, use no-bet bands to avoid noise.
Take Process, Not Luck
Measure model calibration and closing-line value over weeks. Monitor where probabilities deviate from results, and adjust ratings, Kelly fraction, and thresholds accordingly.
Common Mistakes & Troubleshooting
Mistakes can quickly build up on the NFL betting spreadsheet unless you identify and prevent them.
Use canonical names and the Teams tab to prevent join errors and misapplied odds.
Use a unique game key, such as Week/Home/Away. Duplicate rows can increase exposure and destroy the closing line value and ROI.
Ensure accurate conversion of American odds to decimal and remove the vig.
Do not use stale lines for closing line value or stakes. Record all odds and note data that is older than two hours.
Do not over-stake. Reduce the Kelly fraction when unpredictability increases. Use daily limits to manage your bankroll.
Audit your actions monthly to identify hidden errors.
Google Sheets vs. Excel
Choose the platform that fits your workflow and scale. The right tool saves time and reduces errors.
Sheets
Pros
Easy sharing
Built-in IMPORT functions
Real-time collaboration

Alternate between Google Sheets and Excel for deep analysis and quick sharing. Ensure both are synced for optimum flexibility.
Compliance and Responsible Play
It is best to bet legally and responsibly to enjoy a lasting and profitable experience.
Legal Compliance
Only engage in betting if your state allows online sports betting. Some states prohibit it, while others have strict regulations. Ensure you meet the age and location requirements, and the limits of deposits if available. Keep receipts and documents, should you be required to report your betting income or for tax purposes.
Spreadsheet Humility
Use the NFL betting spreadsheet as a tool to support your decisions, not a promise of a win. Review the outcomes and admit your mistakes. Keep refining the spreadsheet and seek feedback from your peers regularly.
Responsible Gaming
Know your limits and maintain discipline for a more responsible betting experience. Let betting remain for fun and not a full-time investment or career. Set time and deposit limits to avoid financial strain. Do not overexert yourself: take breaks, and consider self-exclusion when necessary. Avoid chasing your losses or betting on emotions.
